Product Overview

The SPHSS13 is a high-performance Hydraulic Servo Module engineered for the ABB Symphony Plus and legacy Bailey Infi 90 Harmony Rack systems. It is designed to provide ultra-precise control over hydraulic actuators in mission-critical applications, such as steam or gas turbine valve regulation. By integrating redundant servo coil outputs and supporting dual LVDT (Linear Variable Differential Transformer) feedback, the SPHSS13 ensures maximum fault tolerance and system availability. The module executes local control strategies—including Proportional (P) and Proportional-Integral (PI) algorithms—to maintain exact mechanical positioning even in high-vibration industrial environments.
